Abstract:
:Neutral and acidic glycolipids were extracted from chicken hearts. The neutral and acidic compounds were separated by preparative thin-layer chromatography into eight and two fractions, respectively. Total hydrolysis by mineral acid, permethylation analysis, and sequential cleavage with exoglycosidases showed the presence of glycolipids that belong to the globo- and gala-oligosaccharide series, i.e., the monohexosylceramides Glc-Cer and Gal-Cer, the dihexosylceramides Gal beta 1-4Glc-Cer and Gal alpha 1-4Gal-Cer, the tetrahexosylceramides GalNAc beta 1-3Gal alpha 1-4Gal beta 1-4Glc-Cer and GalNAc alpha 1-3GalNAc beta 1-3Gal alpha 1-4Gal-Cer (III3GalNAc alpha-Ga3Cer) and four subfractions of the Forssman glycolipid GalNAc alpha 1-3GalNAc beta 1-3Gal alpha 1-4Gal beta 1-4Glc-Cer. With the notable exception of III3GalNAc alpha 1-Ga3Cer, all glycolipids with terminal GalNAc alpha 1-3GalNAc1 reacted on thin-layer chromatograms with a monoclonal anti-Forssman antibody. The major components of the acidic fraction glycolipids were characterized as the lactose-based gangliosides Glac1 (GM3) and Glac2 (GD3).
